At least two prison inmates were killed and between 100 and 150 inmates and corrections officers were injured late Wednesday after a gas explosion at a Florida Panhandle jail. The explosion occurred around 11:30 p.m. CDT Wednesday in Escambia County jails booking facility and caused the building to partially collapse, Kathleen Castro, the countys public information manager, told the Associated Press. About 600 inmates were in the building at the time, she said. There has been major flooding in the area, but authorities did not immediately know if there is a connection with the explosion.
